WIRE=COILER.

SPECIFICATION forming part of Letters Patent No. 554,929, dated February18, 1896.

Application iiled November 16, 1895. Serial No. 569,173. (No model.)

To all whom it may concern:

Be it known that I, CHARLES H. HARD, of Oneida, in the county ofMadison, in the State of New York, have invented new and usefulImprovements in W ire-Coilers, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and eX- actdescription.

This invention relates to the class of wirecoilers which are employed inmachines for weaving wire mattresses.

In the operation of said machines it is found that the holder of thecoiling-mandrel requires frequent repairs or removal owing to the wearand abrasion of the interior of said holder by frictional contact withthe wire during the process of ceiling the same, and thus causesconsiderable loss of time andincurs frequent expense.

The object of this invention is to obviate said defects; and to that endthe invention consists, essentially, in the combination, with theceiling-arbor and its holder, of a sleeve or bushing interposed betweensaid parts to receive the wear from the wire in process of being coiled;and the invention also consists in a novel con struction of itscomponent parts, which are adjustable in relation to eachother, so as togreatly prolong the life of the aforesaid sleeve or bushing, all ashereinafter fully described, and specifically set forth in the claims.

In the annexed drawings, Figure'l is a side i elevation of that part ofa wire-coiling machine to which my invention pertains. Fig. 2 is anenlarged side view of the wire-eoiler wit-h parts of the feed-rollerswhich force the Wire through the coiler. Fig. 3 is an enlarged detachedlongitudinal section of wire-coiler embodying my invention, and Figs. 4.and 5 are transverse sections respectively on lines XXandYYinFigS.

Similar letters of reference indicate corre spending parts.

a represents the coiling-arbor, which is provided with the usual spiralgroove a', through which the wire is forced longitudinally, and is thuscoiled into a prolonged spiral. Said arbor is sustained stationary inthe holder 7L, which is rigidly secured to the pillow-blocks A, in whichare journaled the feed-rollers R R, which force the wire through thecoiler. Said rollers receive rotary motion from intermeshing gears C C,fastened to the shafts of the rollers and driyen by suitable mechanism,not necessary to be shown in this case.

D denotes the reel upon which is wound the wire and from which it passesthrough the guide f to the feed-rollers R R, as shown in Fig. 1 of thedrawings.

The holder h is provided with the passage h for the end of the arbor aad jacent tothe rollers R R. From said passage to the opposite end ofthe holder is a cylindrical socket i, formed inside of said holder, andin said socket is seated the sleeve b, which projects from the end ofthe holder and receives through its entire length the ceiling-arbor a,which it loosely embraces. Said sleeve serves to protect the holder hfrom wear from the wire in process of being coiled, and it is formedwith a smooth cylindrical bore to allow it to be turned and adjusted onthe arbor, so as to cause different portions of the bore to receive thefrictional contact of the wire, thus greatly prolonging the life of thesleeve. A set-screw C passes through the side of the holder and bears onthe sleeve h, so as to fasten the latter in its aforesaid adjustedposition.

On the protruding end of the sleeve is mounted a collar e, which abutsagainst the end of the holder h and is provided with a radial orificewhich is screw-threaded and receives through it the screw-threadedportion of the set-screw d, the inner end of which passes through a holeh in the side of the sleeve h and engages the arbor a, so as to confinethe same in the sleeve. In order to allow the sleeve to be reversed endfor end and thus change its position in relation to the wire-coilinggroove a, as hereinafter described, I provide the sleeve with two holesb', respectively, in opposite end portions thereof, as shown in Fig. 3of the drawings.

It will be observed that the sleeve b relieves the main portion of theholder h from wear and abrasion from the wire passing through thecoiling-groove a', and inasmuch as said sleeve is detachable from theholder and from IOO the arbor it is readily removed for repairs orrenewal without requiring any repairs of the holder h.

The advantages of the use of the sleeve l) are greatly enhanced by itsadjustability in relation to the eoiling-arbor a, one of whichadjustments is effected by simply loosening the set-screws c and (Z,then turning the arbor so as to bring the groove a' into a diferentposition in the sleeve b and then securing it in said position bytightening the set-screw d, and, after turning the sleeve with the arborfastened thereto so as to bring the Wire-receiv ing end of the arbor inproper position on the holder 7L, tightening the set-screw c.

Inasinuch as it requires only a slight turning of the arbor in thesleeve to effect the aforesaid adjustment, it is obvious that it admitsof numerous adjustments of that kind. IIowever, the degree of adjustmentis still further extended by reversing thelsleeve l) end for end, forwhich purpose said sleeve is provided with the two holes b' 1) inopposite end portions for the reception of the set-screw d, ashereinbefore described.

That I claim as my invention is- 1. The combination of the holder 7Lprovided with the passage h and cylindrical socket i, the sleeve ZJseated in said socket and projecting from the end thereof, thecoiling-arbor CL extending through said sleeve, the set-screw cconfining the sleeve adj nstably in the holder,

and the set-screw (Z holding the arbor adjustably in the sleeve, as setforth.

2. The combination of the holder h provided with the passage 7L andcylindrical socket t', the sleeve l) seated in said socket andprojecting from the end thereof and provided with the holes b b in thesides of bot-h end portions thereof, the arbor a extending through saidsleeve, the set-screw@ fastening the sleeve ad justably in the holder,and the setscre\v (l passing through one of the aforesaid holes in thesleeve and engaging the arbor, substantially as set forth and shown.

3. The combination of the holder h provided with the passage h andsocket i, the sleeve l) seated in said socket and projecting from theend thereof, the coiling-arbor a extending through the sleeve, thecollar e mounted on the protruding end of the sleeve and abuttingagainst the end of the holder, the set-screw c fastening the sleeve adjustably in the holder, and the set-screw d passing through the side ofthe aforesaid collar and sleeve and en gaging the arbor, substantiallyas described and shown.

In testimony whereof I have hercu nto signed my name this 41h day ofNovember,

CHARLES 1I. HARD.
